3. PSC aims to incorporate emerging Web services into ubiquitous computing for facilitating people daily individual-based and group-based activities, respectively supported by service collaboration and service coordination. PSC vision 2/3/2010 PSC presentation@Motive workshop, Espoo

5. PSC-Oulu objectives 2/3/2010 PSC presentation@Motive workshop, Espoo To research and develop a pervasive service computing model and a description language To research and develop a service collaboration framework to strengthen the capability of collaboration in a pervasive computing environment To research and develop a service coordination framework to strengthen the capability of coordination in a pervasive computing environment

7. Solution 1: Seek a service composition consisting of a set of services within one party for achieving the travel reservation goal.

8. Solution 2: Seek an optimal service composition consisting of a set of services within one party for achieving the travel reservation goal taking into account constrains of service properties of cost, time, etc

9. Solution 3: Seek a service composition consisting of a set of services among multiple partiesfor achieving the travel reservation goal

10. Solution 4: Seek an optimal service composition consisting of a set of services among multiple parties for achieving the travel reservation goal taking into account constrains of service properties of cost, time, etcA generic user activity scenario
